Liquid crystal display wherein each pixels of first layer is optically aligned with respective group of pixels of second layer

摘要

A color display includes a first layer of pixels, each of which has an independently controllable light attenuation so as to control the display intensity of each display pixel independently. A second layer of pixels is provided in which the color of each pixel can be independently controlled. Thus, each effective display pixel can be controlled, independently of the other pixels, with respect to its intensity and chrominance.
